Since I don't have a lot of information about this novel, it's hard to say exactly who the main characters are. However, we can assume that there is likely a protagonist who harbors this dark thought about another character, perhaps an antagonist or someone who has wronged the protagonist in some way in the story.
Well, it could be centered around the idea of emotional turmoil. In many novels, when a character expresses such a strong negative sentiment, it often reflects on the overall state of the relationship in the story. Maybe it's about two characters who have had a long - standing feud or some sort of misunderstanding that has led to this extreme feeling.
Often in a novel with such a title, there might be a protagonist who is deeply conflicted, perhaps a character who has been wronged in some way by another character. So the main characters could be a victim - like figure and the antagonist who has caused the pain. However, without reading the book, it's just speculation.
Another aspect of the main theme could be related to the exploration of human emotions in extreme situations. The title 'There was time i wish you were dead' is quite intense, so the novel might be about how people deal with such intense emotions, whether they are able to move past them, or if they let these emotions consume them. It could also touch on themes of forgiveness and redemption, or the lack thereof.
It's an exciting tale with elements of fantasy and adventure. The theme often involves battles between good and evil, and the pursuit of power and desires.
The plot of 'A Demon's Wish' manhwa involves a demon whose wish sets off a chain of events in a magical world. There are battles, mysteries to solve, and characters with complex motivations.
Well, one big spoiler is a surprise romance development that you wouldn't expect. Also, there's a crucial decision made by a supporting character that has huge consequences. But it's better to discover these yourself while reading.
